This is a Kuretake empty pen. You can make your own pen using your favorite ink. I bought it, but I'm selling it because I haven't had a chance to use it. It's unopened, but it has been stored at home, so please purchase only if you don't mind. I will put it in an envelope and ship it via Yu-Packet Post. Please read my profile, and if you have no questions, you can purchase it as is. Thank you.
